Fig. A.2
Variations of the distance and the apparent speed of component C8 assuming a constant bulk Lorentz factor γc ≈ 5.5. Top pannel: from the plot of the variations of the distance we deduce the mean speed: 4.86 mas/19.7 yr ≈247 μas/yr. Bottom pannel: despite the high value of the inclination angle, we observe a superluminal motion with a mean speed ≈4.1 c.
